I see that the chromakey is something I can set via XvSetPortAttribute(). I
also see what you mean about not directly putting the image and drawing the
data to the window.
The following sequence seems to be working well:
For each video frame:

You'll want to query the attributes first though. If the at
Most drivers implement XvShmPutImage as a video overlay. That
means it's not "draw" into the window. It was not the intention
that one should be able to render XvShmPutImage into a window along
with normal Xlib rendering, subsequently, that type of thing is not
supported in the general case.
